Also white (but high emissivity) paint. Painting every dark urban and suburban surface white would reduce total radiative forcing somewhere around a watt.

White paint gets covered with grime and turns dark. It also flakes off and degrades into microplastics and toxic crud. Either way it requires ongoing maintenance and regular repainting.

Leaves, otoh, are self-healing and 100% biodegradable.

Sure, if you have to paint something anyway, you may as well use reflective paint. But wherever you can put a tree you should.
